INSTALLATION MANUAL MULTIFUNCTIONAL SURFACE MOUNTED ROLLER SHUTTER VR150
5.2. The wall cardan joint
− The cable duct or tape guide is usually found in the shutter unless otherwise requested.
It is important, however, to ensure there is a cardan joint before starting the installation.
− Measure the distance of the cardan joint (motor cable, gearbox, tape operation) on
the shutter box and mark the position on the wall or window frame. The easiest way
to determine this position is by placing a guide rail in the correct position against the
wall. Use the top of the guide rail as a point of reference.

− Carefully drill from the outside to the inside of the wall (bore hole 10 mm for motor
cable, 14 mm for crank, 20 mm for tape guide). A tube is pressed into the hole for
the tape guide to prevent damage to the tape.
− When drilling through the wall you will achieve the best results if, while drilling, someone
exerts some pressure against the inside of the wall with a piece of wood or something
similar. Use a rotating drill rather than a hammer drill for the last part.
− When drilling through the window frame make sure that you do not drill into the
glass section!
